Like always, we were looking on the internet “googling” away for a DOF calculator and couldn’t find a good one, so we decided to make our own. if you know about DOF, jump down to the bottom of the post or follow the link here to depth of field calculator if not read on about how depth of field works.

This post is about the DOF – depth of field calculator. what is DOF?

Answer: Wikipedia on DOF
In optics, particularly as it relates to film and photography, the depth of field (DOF) is the portion of a scene that appears acceptably sharp in the image. Although a lens can precisely focus at only one distance, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.

In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus.
The DOF is determined by the camera-to-subject distance, the lens focal length, the lens f-number, and the format size or circle of confusion criterion.
For a given format size, at moderate subject distances, DOF is approximately determined by the subject magnification and the lens f-number. For a given f-number, increasing the magnification, either by moving closer to the subject or using a lens of greater focal length, decreases the DOF; decreasing magnification increases DOF. For a given subject magnification, increasing the f-number (decreasing the aperture diameter) increases the DOF; decreasing f-number decreases DOF.
When a picture is taken in two different format sizes from the same distance at the same f-number with lenses that give the same angle of view, the smaller format has greater DOF. When a picture is taken in two different formats from the same distance at the same f-number using lenses of the same focal length, the smaller format has less DOF.
Cropping an image and enlarging to the same size final image as an uncropped image taken under the same conditions is equivalent to using a smaller format under the same conditions, so the cropped image has less DOF.

When focus is set to the hyperfocal distance, the DOF extends from half the hyperfocal distance to infinity, and the DOF is the largest possible for a given f-number.
The advent of digital technology in photography has provided additional means of controlling the extent of image sharpness; some methods allow extended DOF that would be impossible with traditional techniques, and some allow the DOF to be determined after the image is made.

Here’s what you been looking for DOF depth of field calculator use this as only a tool, we are not responsible for any mis calculations or any un-sharp images that are taken from this calculator.

Happy shooting and hope you enjoy your next photo session. aloha!

We were looking online and found a post on another photo blog about a photoshop action to make this polaroid montage, but when we went to download the file, it was no longer available. We decided to make our own action and share it with you. if you haven’t used actions with photoshop, it is an automated task so that you don’t have to do it manually. hope you enjoy this photoshop action, enjoy and have fun with it.

Sacrifice your next cup of coffee and donate $3.99 to support this website. Aloha!

Good luck and enjoy!

Aloha and welcome to thedigidarkroom.com by bradyoshiro.com.are you ready to launch your photography off the ground and make some awesome images? if your answer is “yes” your in the right place.

A small introduction about us before we go off into the wild wild west of digital photography. We have been shooting photography for the the last decade and have entered into the industry at the start of the digital revolution, where everything is digital with a world full of gadgets. We started off shooting surf photography and now shoot weddings. We have experimented in fashion, portrait, landscape and all kinds of photography along the way, enough to get into trouble. but we would have to say our strengths are in surf and wedding photography.

The whole reason we wanted to start this site, is because two friends (www.bradyoshiro.com) (www.davecollyer.com) talking shop about the latest cameras trends and how we could improve our photography. Instead of keeping it to ourselves we have decided to share some our experiences and knowledge with you.

So continue reading and start from anywhere you want as we go over the basics of photography, equipment, techniques, workflow, and wherever else this site and photography will take us.

Well, enough nonsense, let get started!!! Mahalo for reading and Happy Shooting!
